SMART MATERIALS: Lightweight & Energy Efficient for Extended Range

composite light-weight flooring

Composite Light-
Weight Flooring

Instead of using heavy marine grade plywood flooring, we utilize high-density polyurethane foam reinforced with layers of fiberglass. The no-rot and light-weight advantages of foam combined with the structural properties of fiberglass make these composite panels an excellent replacement material for wood. In addition, we also utilize light weight rubber flooring to reach a combined weight savings of over 600 pounds, while having stronger rot and corrosive resistance to the elements.

energy-efficient LED lighting

Energy-efficient LED
Lighting

By utilizing LED Lighting throughout the bus we have cut down the lighting energy consumption by two-thirds. The life of a high-power white LED is projected to be from 35,000-50,000 hours, compared to 750-2,000 hours for an incandescent bulb. A conventional light bulb wastes most of its energy as heat. For example, an incandescent bulb gives off 90 percent of its energy as heat, while a compact fluorescent bulb wastes 80 percent of its energy. Since LED contain no glass components, they are not vulnerable to vibration or breakage like conventional bulbs.

All Electric Drive
System

The ZEPS bus includes state-of-the-art inverter and motor technology. The system provides maximum torque at start and smooth acceleration profile. The High voltage distribution and DC-DC converters are integrated into a single box to reduce number of components and improve product reliability. The system operates at 350V DC giving perfect balance of safety and performance. The intelligent telemetry system collects all critical system parameters allowing remote monitoring and troubleshooting.

Intelligent Climate
Control System

Intelligent Climate control system is critical for passenger comfort. The ZEPS bus provides intelligent climate control that maintains perfect internal temperature in all-weather conditions. The all-electric roof top mounted air conditioning system provides uniform cooling at all vehicle speeds and loads. The energy efficient system is twice as efficient as traditional water based cooling systems and is 50 percent lighter in weight.
